Ford cars slow when they see speed-limit signs

Ford’s Latest Technology Involves Using Cameras to Keep You From Driving Too Fast, but Is That Really All They Will Do?.

The automaker’s newly-introduced technology, called Intelligent Speed Limiter, works by letting drivers set their “maximum speed” on the road by using steering wheel controls. Once a maximum speed is set, the vehicle can then restrict the fuel flow to the engine if it reaches a speed that’s above the posted speed limit, the Daily Mail reported. By using a windshield-mounted camera to monitor road signs drivers might not see, the technology can not only keep cars from driving too fast, but it can also detect objects and pedestrians in their path.

If the car is speeding down a hill where fuel restriction might not make much of a difference while slowing it down, an alarm would sound to let the driver know they need to apply the brakes. The system also communicates with the onboard navigation to help accurately maintain the appropriate maximum speed when distances between speed limit signs are greater. Consider this scenario: the windshield-mounted camera detects an object in the roadway that doesn’t necessitate a full-stop, like a cardboard box or a small dead animal.
